Part 2: Lactation and management of dairy cattle.  In rural locations, pigs and poultry can obtain much of their nutrition from scavenging, and in African communities, hens may live for months without being fed, and still produce one or two eggs a week. The birds may be harvested on several occasions or the whole shed may be cleared at one time. , In northern Europe, agriculture including animal husbandry went into decline when the Roman empire collapsed.  Historic farms such as those in the United States offer farmstays and "a carefully curated version of farming to those willing to pay for it", sometimes giving visitors a romanticised image of a pastoral idyll from an unspecified time in the pre-industrial past. Selective breeding involves using knowledge from several branches of science. The mechanized and chemical methods used are causing biodiversity to decline. , The Nile provided a plentiful source of fish. , At the other extreme, in the more developed parts of the world, animals are often intensively managed; dairy cows may be kept in zero-grazing conditions with all their forage brought to them; beef cattle may be kept in high density feedlots; pigs may be housed in climate-controlled buildings and never go outdoors; poultry may be reared in barns and kept in cages as laying birds under lighting-controlled conditions. The Animal Science major prepares students for study in veterinary medicine or careers in animal production, biotechnology and conservation and has been nationally recognized for its work in animal breeding and genetics, nutrition, physiology, growth, behavior and management. Two or more genes may be associated with a specific locus and therefore with a specific trait. Cows produce some 570 million cubic metres of methane per day, that accounts for from 35 to 40% of the overall methane emissions of the planet. , Animals used as livestock are predominantly herbivorous, the main exceptions being the pig and the chicken which are omnivorous. Alternatives to animal testing were proposed to overcome some of the drawbacks associated with animal experiments and avoid the unethical procedures. Whole bays, lakes or ponds may be devoted to aquaculture, or the farmed animal may be retained in cages (fish), artificial reefs, racks or strings (shellfish). Works have started across the Budj Bim Cultural Landscape, as part of the Victorian Government’s support for the Gunditjmara Traditional Owners to protect and develop the land so more people can celebrate its history and cultural significance.  These sheep were exported widely and have contributed to numerous modern breeds. The Faculty of AgriSciences at Stellenbosch University (SU) is held in high esteem at national and international levels for the quality of its training and research and also as consultant in the agricultural and forestry industry. Animal Physiology. Genetic gains made using additive genetic effects are permanent and cumulate from one generation to the next. Animal breeding, controlled propagation of domestic animals in order to improve desirable qualities. , Since the 18th century, people have become increasingly concerned about the welfare of farm animals. Camels were domesticated soon after this, with the Bactrian camel in Mongolia and the Arabian camel becoming beasts of burden. The Lincoln Longwool was improved by Bakewell and in turn the Lincoln was used to develop the subsequent breed, named the New (or Dishley) Leicester. This virus is easily transmissible to domestic poultry, and to humans living in close proximity with them. The crickets are kept in pens, boxes or drawers and fed on commercial pelleted poultry food, while the palm weevil larvae live on cabbage palm and sago palm trees, which limits their production to areas where these trees grow.
